Reply #6: A Very Short But Explaining Answer

[medienanalyse]

"Why does a plane that leaves the bigger entrance hole NOT manage to crash through 200 feet of the apparently less solidly built WTC when on the other hand a smaller plane manages only a small entrance hole at the Pentagon still is capable to crash through 310 feet of what apparently is much more solidly built?"

Answer: the difference between the buildings in this question is: alu-shredder inside vs. alu-shredder outside.

Additionally: forget about the solidity of a building. Solidity is a function to many circumstances from weight to earthquakes, from wind-thrust to construction principles.

And as always I repeat: do not forget the kevlar on the walls ...
